摘　　要：针对精确、规则、无冗余性的矢量工程图纸,研究与实验了一种水印嵌入与识别算法,同时注入两类水印信息即隐藏扩展信息和基于长度影子震荡的空间域水印信息,实验取得了预想的结果,在保持矢量工程图纸适当精度和图面信息基本完整的情况下,水印具有良好的鲁棒性。Aiming at the precise,rules,no redundancy of the vector engineering drawings,this paper studies and experiments a watermarking embedding and recognition algorithm,embedding two kinds of watermarking information（hidden extend information and spatial shadow concussion based on length variation）.This experiment made desired results,and watermarking has good robustness when maintain the vector engineering drawings precision and appropriate appearances.
